Abstract

Die Erfindung betrifft ein Dosierventil an Dosierpumpen, insbesondere für die Abdosierung von fließfähigem, stückige Feststoffteile enthaltendem Dosiergut, wie Marmelade, Joghurt od. dgl., und geht aus von einem Dosierventil nach der DE-A-195 04 546 Um für eine Dosierpumpe sowohl für das Ansaugen als auch das Ausstoßen des Dosiergutes mit nur einem solchen Dosierventil auszukommen, ist erfindungsgemäß vorgesehen, daß die beiden Zu- und Abflußkanäle (9,10) im Gehäuse (2) im wesentlichen gegenüber einer Pumpenansaug- und Ausstoßöffnung (11) und die durch einen Zwischensteg (12) distanzierten Öffnungen (9',10') der Zu- und Abflußkanäle (9,10) in der zylindrischen Verstellebene (ZE) der Schließfläche (6) des Nockens (5) angeordnet sind, wobei der Radius (R) der Schließfläche (6) kleiner ist als der Radius (R') des Hohlraumes (8) außerhalb des Bereiches der zylindrischen Anordnungsebene (ZE') beider Öffnungen (9',10'), und daß die Schließfläche (6) in ihrer Bogenlänge (L) derart bemessen ist, daß bei entsprechender Stellung des Nockens (5) mindestens die beiden Öffnungen (9',10') verschlossen sind oder maximal die Bogenlänge (L) sich vom einen oder anderen Öffnungsrand (11') der Pumpenansaug- und Ausstoßöffnung (11) zum jeweils inneren Öffnungsrand (9''',10''') der einen oder anderen Öffnung (9',10') erstreckt.

The invention relates to a metering valve on metering pumps, in particular for the metering of flowable, piece-like solid-containing items to be metered, such as jam, yogurt or the like, and is based on a metering valve according to DE-A-195 04 546 order for a metering pump for both the suction as well as the ejection of the dosing material to get by with only one such dosing valve, the invention provides that the two inflow and outflow channels (9, 10) in the housing (2) essentially opposite a pump suction and discharge opening (11) and through an intermediate web (12) spaced openings (9 ' , 10 ' ) of the inflow and outflow channels (9,10) are arranged in the cylindrical adjustment plane (ZE) of the closing surface (6) of the cam (5), the radius (R) the closing surface (6) is smaller than the radius (R ') of the cavity (8) outside the region of the cylindrical arrangement plane (ZE') of both openings (9 ', 10'), and that the closing surface (6) in its B eye length (L) is dimensioned such that, when the cam (5) is in a corresponding position, at least the two openings (9 ', 10') are closed or at most the arc length (L) extends from one or the other opening edge (11 ') of the pump suction and ejection opening (11) to the respective inner opening edge (9 ''',10''') of one or the other opening (9 ', 10').
